TL L5-2451cc 2.5L SOHC MFI (1997)
When the vehicle is stopped, the power steering speed sensor functions operate only the low speed valve. Because the low speed valve has the small
chamfer and thereby the small opening area, high fluid pressure can be fed to the power cylinder with the small displacement angle (small steering
torque), resulting in light steering (high assist).
When driving the vehicle, the fluid is applied to the high speed valve, too, as the vehicle speed sensor functions. Because the high speed valve has a
large chamfer and thereby the large opening area, the opening area of the two valves is compounded, even though the displacement angle is the same
as when the vehicle is stopped. Therefore, the fluid pressure is not generated unless the displacement angle is large (large steering torque), resulting in
moderately heavy steering (medium assist).
